Seahawks open on top of NFL Power Rankings

After steam-rolling the Denver Broncos in the Super Bowl, it should come as no surprise that the Seattle Seahawks open the 2014 season on top of the TSN.ca NFL Power Rankings.

The Seahawks have a devastating defence and could be at an even higher level than last season if they can somehow keep wide receiver Percy Harvin healthy. It's never easy to repeat a championship in pro sports, but the Seahawks will at least have a viable chance to go back-to-back this season.

Even though they were blown out in the Super Bowl, the Broncos are still ranked second. Adding DeMarcus Ware and Aqib Talib should provide more playmakers on the defensive side of the ball, which is the big question for the Broncos.

Most of the top contenders, though, are in the NFC. Behind the Broncos, the New Orleans Saints, San Francisco 49ers and Philadelphia Eagles are teams that recorded double-digit wins last season and are viable challengers for the Seahawks and Broncos.

Some of the teams making moves up, going into the season with higher expectations, include the Detroit Lions, who are in the Top 10, the Tampa Bay Buccaneers, who vaulted into the Top 20.

At the other end of the spectrum, the Jacksonville Jaguars, St. Louis Rams and Oakland Raiders hold the bottom three spots, though there are several other teams that could easily slide into those dubious spots.
